"An update for collectd is now available for RHEV 4.X RHEV-H and Agents
for RHEL-7 and RHEV Engine version 4.1.

Red Hat Product Security has rated this update as having a security
impact of Moderate. A Common Vulnerability Scoring System (CVSS) base
score, which gives a detailed severity rating, is available for each
vulnerability from the CVE link(s) in the References section.

collectd is a small C-language daemon, which reads various system
metrics periodically and updates RRD files (creating them if
necessary). Because the daemon does not start up each time it updates
files, it has a low system footprint.

The following packages have been upgraded to a newer upstream version:
collectd (5.7.1). (BZ#1446472)

Security Fix(es) :

* collectd contains an infinite loop due to how the parse_packet() and
parse_part_sign_sha256() functions interact. If an instance of
collectd is configured with 'SecurityLevel None' and with empty
'AuthFile' options an attacker can send crafted UDP packets that
trigger the infinite loop, causing a denial of service.
